I don't think so, most teams never do the last 10% on any project ever. They pick the low hanging fruit with the first 80% and if they are thorough they might bring it up to 90%, but 100%? I've never seen such a software project.

I'd say that Total Commander is very close to 100%.

TeX82 as well. From https://en.wikipedia.org/wiki/TeX#TeX82:

> Since version 3, TeX has used an idiosyncratic version numbering system, where updates have been indicated by adding an extra digit at the end of the decimal, so that the version number asymptotically approaches π. This is a reflection of the fact that TeX is now very stable, and only minor updates are anticipated. The current version of TeX is 3.141592653; it was last updated in 2021.
